Application filed May 2,

To all whom it may concern Be it known thatl, CHARLES E. Kant, a citizen of the United States, residing at Binghamton, county of Broom'e, and State of New York, have invented certain new and useful Improvements in Egg Beaters, of

which the following is a Specification.

This invention relates-to'eggbeaters, and particularly to hand-operated heaters in which two beater elements may be simultaneously rotated in opposite directions by turning an operating wheel.

An important object of this invention is to provide a beater of the t pe referred to in which all parts are so orrned and arranged that adjacent surfaces thereof may be readily cleaned, so that the beater, as a Whole, may be kept in hygienic condition.

Another object is to provide such a heater which is more durable than prior heaters, while being lighter and less expensive to manufacture.

A further object is to so relatively arrange the parts of such abeater that it may be more conveniently operated, and so that the parts will be subjected to less strain than prior heaters.

l Vith these and other objects in view, some of which other objects will be obvious and others will be hereinafter specifically pointed out, this invention consists of certain features of construction and arrangement of parts more fully described in the following r specification and shown in the accompanying drawing which forms part thereof, andin which- Figure 1 is a side elevation of an egg; beater embodying this invention,

Fig. 2 is a rear elevation of the beater of? Fig. 1,

Fig. 3 is a plan view of the beater of Figs. 1 and 2, and

Fig. l is a fragmentary view, partly in section, of certain parts ofthe beater o-f'Figs.

1,2and3.

Referring to Fig. 1,-the strip metal locate inp; elements 21, 21 are journaled upon the frame 22; and the upper ends o-fsaid elements extend through and' are hent over above openings provided therefor in the pinions 23, 23, which p inio'nsf'are jouina'led.

upon the upper portions'of the frame 22.

The body member-24E has a handle 25 formed at one end thereof andhas lugs 26,

1222. Serial No. 557,210.

26 formed near the other end thereof for holding the upper ends of the frame 22. The perforated cars 27, 27 are formed from the member 2a and are situated intermediate the handle 25 and the lugs 26, 26, and the shaft 28 is journaled in the perforations 0 said ears to rotate freely therein.

The driving wheel 29 is fixed upon an end of the shaft 28, and said wheel carries the handle 30 for operation thereof. As best shown by Fig. 4, the shaft 28 has a shoulder 31 from which a reduced diameter portion 32 extends through the washer '33 lid and the center hole of the wheel 29; said portion 32 being riveted over at 34: outside Y the wheel 29, so that the teeth 35 of said I wheel will be rigidly niaintainedinv a plane perpendicular to the axis of said shaft.

The ears 27, 27 are spaced apart such dis tance that, when the shaft 28 is journaled therein, the teeth 35 will be maintained in substantial alignment with the major axis of the member 24: notwithstanding the clearance between the shaft 28 and the walls of the perforations in said ears which provides a free running fit therebetween, even when such clearance is augmented by considerable enlargement of such perforations, such as may result from extended use of the beater. The one of the ears 2'? which is situated nearest to the wheel 29 is disposed at such distance outside of the general outline of the member 24- as to provide ample space be tween the rear face'of said wheel and the edge of said member so that such parts may be readily cleansed. The rear end of the shaft 28 is riveted over so as to form a 2'7 so as to prevent excessive end-chase of the shaft 28, while permitting said shaft to rotate freely.

The diameter of the wheel 29 is such that the teeth 35 thereof will effectively engage those of one of the pinions 23, 23- when the shaft 28 occupies its intended position in the perforations ofthe ears 27 and the bentover ends of the elements 21, 21 above said pinions rest against member 4 The teeth of the wheel 29, and those of the pinions 23, 23, are disposed at an angle of approximately to the faces thereof, and all at said teeth are eshaped, of

the lower end of the 1 llt this throughout anexceptionally long period of length at least five times the thickness of the sheet metal from which they are cut,

and are so positioned that the spaces therebetween are not less than one and one-half times the circumferential area or thickness of said teeth.- Because of the shape, the spacing and. the disposition of saidteeth relative to their axis of rotation, as just described, they roll very freely even when set to mesh more deeply than would be practicable in ordinary spur and bevel gear practice, so that the effectiveness of their operation is not impaired by comparatively wide changes in relative positioning of their centers of rotation; and said teeth act equally well when meshing between gears whose axes of rotation are disposed parallel or at any angle to one another.

The member 24 is twisted between the ears 27, 27 and the handle 25,'s0 that the axis of said handle is disposed at an angle of approximately 60 from the axis of the shaft- 28, for a reason which is hereinafter more fully explained.

For the larger sizes of egg-heaters, two lugs, such a the lugs 26, are provided for holding each of the ends of the frame 22; for the smaller sizes, it may be considered preferable to employ but one such lug for each frame end. If two lugs are provided for holding each of the frame ends, the material of the frame may be swaged between said lugs, as shown, for the purpose of preventing endwise movement of said frame through the channels provided by said lugs.

In any event, such frame ends should be securely fastened in the lugs in some suitable manner. It hasbeen found to be desirable to somewhat swage the portions of the legs of the frame 22 directly below the ,pinions 23, 23, as at 37 (see Fig. 4), so as to prevent excessive movement of said pinions along the lengths of the legs of said frame away from the end of the member 24.

In the use of the beater shown, the handle 25 is encircled by the fingers of one hand of the user, the portion of the body member 24 immediately adjacent to said handle passing between the fingers; and the wheel 29 is thus presented for convenient operation by the other hand of the user. The axis of rotation of said wheel will then be sub stantially in alignment with the arm of the hand of the user which grasps the handle 30 and operates the wheel 29. Because of the peculiar arrangement of the teeth of the wheel 29 and of the pinions 23, 23, the beater operates with a minimum of friction and irregularity; and, because of the various features of construction already described, vbeater will operate successfully use. I

It is believed that the construction and use of thi invention is so clearly disclosed by the accompanying drawing and the fore going description, that those skilled in this art will fully comprehend same, without further description thereof herein.

it should be understood that features of this invention are adapted for use, either singly or in groups comprising less than all of such features, in combinations eml3()(l 'lnlf forms of structure heretofore em ployed for purposes analogous to other features of this invention.
